|---|---|
| Proxy listen path | Enter the path where the proxy should listen for incoming connections. To listen to all paths, select "[All]" from the drop-down menu. No two message proxies can have HTTP proxy connections with the same proxy path or with a path that matches an existing virtual asset’s HTTP path. See Service Forward Path and Proxy Listen Path for more details. |

It will not pass the redirect back to the client. See Service Forward Path and Proxy Listen Path for more details. |
Secondary Connection (outgoing)
Enable the Use secondary connection if primary fails option if you want traffic to be redirected to a secondary proxy endpoint when the primary connection fails or the responder is not available. The connection will be considered "failed" if the response status code is 400 level or higher.

Options
Mode: Allows you to set the active forwarding connection when a primary and secondary connection exist. For example, during a recording session, a message proxy may forward to the live service as the primary connection and fall back to a virtual service as a secondary connection. In this case, you can set the HTTP mode to Primary and enable Use other connection if selected mode fails.
Once recording is complete and new virtual assets are generated, you may want to re-configure the proxy to forward to the virtual service first and fall back to the live service if a failure occurs. This change can be quickly applied by right-clicking the proxy and switching the HTTP mode to "secondary". The failover will be adjusted accordingly at runtime.
Use other connection if selected mode fails: Enable this option if you want traffic to be redirected to the backup proxy endpoint when the active connection (as determined by the Mode selected above) fails. The connection will be considered "failed" if the response status code is 400 level or higherFor instance, you may specify a secondary endpoint if you want a virtual asset to be used whenever the live endpoint is unavailable. If a virtual asset does not handle a given use case, you may also use a secondary endpoint to redirect traffic to the live endpoint and record the live traffic for creating a new virtual asset to cover that use case.
If this option is not enabled, the primary active connection will be used for recording.
If this option is enabled, you can select a recording option from the available recording options (described below).
Recording options
These settings determine how to record traffic when a secondary endpoint is specified.
Record dropdown:
- Both Record on both connections: Records traffic for both the primary and secondary connections. Error messages from the primary active connection will not be recorded; instead , the messages will be sent to the secondary backup connection and the responses will be recorded. Errors reported by the secondary backup will be recorded.
- Record on primary Primary connection only: Records traffic for the primary active connection. Does not record errors.
- Record on secondary Secondary connection only: Records traffic for the secondary backup connection, including errors.
...
The Service SSL section needs to be completed only if the service you are working with uses SSL.
If the service being virtualized and/or the application under test uses SSL and/or other authentication (basic/digest, Kerberos, NTLM), additional configuration may be required.
...
To specify proxy settings at this level, provide the appropriate details in the proxy’s Proxy Server tab.
SSL is not supported.
...
- Set the service host and port to that of the Virtualize Server where the virtual asset is deployed. If you want the proxy to foward forward to a virtual asset on the local server without consuming an HTTP connection, enter,
localhosthost.virt.internal,localhost, or127.0.0.1rather than the actual host name. hostname. When using localhost or127.0.0.1,the service port must match the port Virtualize is deployed on; when usinghost.virt.internal,the service port is not used. - Set the proxy connection’s Service forward path to the virtual asset’s path (found in the virtual asset’s Transports> HTTP tab, under HTTP endpoint).
...
You can create a properties file to configure additional Reverse Proxy HTTP listener Listener settings. The properties file allows you to fine-tune Reverse Proxy HTTP listener Listener performance and specify additional SSL settings.
- Create a plain text file and specify the properties you want to set (see Reverse Proxy HTTP Listener Message Proxy Performance Properties and Reverse Proxy HTTP Listener Message Proxy SSL Properties).
Save the file to theVirtualAssets the VirtualAssets or TestAssets directory in your workspace and name it
embeddedServer.properties.
The file will be read every time a proxy with a Reverse Proxy HTTP listeners Listener is enabled.

Assume that we want to create a message for a service that is normally accessed at http://example.parasoft.com:9080/BookStore. We could create an HTTP Reverse proxy with the settings:
- Proxy listen path: /BookStore
- Service host:example.parasoft.com
- Service port: 9080
- Service forward path: [empty]
This configuration will listen on /BookStore and forward all traffic to the actual book store service.
If we wanted to listen on a path other than the service path, we would configure change the configuration of the proxy as follows:
- Service forward path: /BookStore
- Proxy listen path: /SomeOtherPath
This would route traffic from /SomeOtherPath on the proxy to the actual book store service.
...
For example, to send traffic to a virtual asset on a remote server, you might use:
- Proxy listen path: /path
- Service host: virtualize.parasoft.com
- Service port: 9080
Proxy listen path: /path
To send traffic to a virtual asset on a local server, you might use:
- Service host: localhost
- Service port: 9080
- Service forward path: /pva
The HTTP Reverse proxy makes no distinction between a virtual asset and an actual service. Both are configured the same way. However if the HTTP Reverse proxy is sending to localhost, you must specify specify Service forward path because the proxy doesn't allow forwarding to itself.
...
Depending on your configuration, you configure either security setting or both.

Additionally, you need to provide the information needed to use a specific key store and certificate so Parasoft can determine which certificate to present to a server (e.g., for 2-way SSL).
